A mountain lion was sighted Sunday in Parking Lot F of the Lawrence Berkeley National Laboratory.

The mountain lion was outside of the lab’s perimeter fence, according to a UCPD Nixle alert released Monday. The animal was not aggressive and later disappeared down the hillside. The area was later searched, but the mountain lion was not found, the alert stated.

There have been multiple mountain lion sightings this year, including one near Stadium Rim Way in September and one near the Clark Kerr Track in July. According to the UCPD alert, several sightings of mountain lions in the past few years have also occurred in the hills above the UC Berkeley campus.

UCPD is advising people not to hike or jog alone, especially between dusk and down, and also to make “plenty of noise” while hiking.
